Boss: The client said the system is broken and it's not working. He said it does nothing.
Programmer: What was he trying to do? Was he registering new customers?
Boss: No.
Programmer: Was it that invoice issue again?
Boss: No. He said he only opened the system and nothing happened.
Programmer: Which button did he press?
Boss: He said none.
Programmer: Let me see: He wasn't registering anyone, neither querying or printing anything. He didn't press any button and the system didn't do anything??
Boss: Yes! That's what he said!
